With a clock interval of 400 nsec and a 64 bit transactions (32 bit preamble & 16 bit control & 16 bit data), it is reasonable to assume the mdio transaction will take 25.6 usec. Add a 30 usec delay before the first poll to reduce the chance of a 1000-2000 usec sleep. Reduce the timeout from 1000ms to 100ms as it is unlikely for the bus to take this long. Signed-off-by:

Jakub Kicinski says: ==================== tools: ynl-gen: fill in the gaps in support of legacy families Fill in the gaps in YNL C code gen so that we can generate user space code for all genetlink families for which we have specs. The two major changes we need are support for fixed headers and support for recursive nests. For fixed header support - place the struct for the fixed header directly in the request struct (and don't bother generating access helpers). The member of a fixed header can't be too complex, and also are by definition not optional so the user has to fill them in. The YNL core needs a bit of a tweak to understand that the attrs may now start at a fixed offset, which is not necessarily equal to sizeof(struct genlmsghdr). Dealing with nested sets is much harder. Previously we'd gen the nested structs as: struct outer { struct inner inner; }; If structs are recursive (e.g. inner contains outer again) we must break this chain and allocate one of the structs dynamically (store a pointer rather than full struct). ==================== Link: https://lore.kernel.org/r/20231213231432.2944749-1-kuba@kernel.orgSigned-off-by: -

To avoid infinite nesting store recursive structs by pointer. If recursive struct is placed in the op directly - the first instance can be stored by value. That makes the code much less of a pain for majority of practical uses. Reviewed-by:

Jakub Kicinski authored
We try to keep the structures and helpers "topologically sorted", to avoid forward declarations. When recursive nests are at play we need to sort twice, because structs which end up being marked as recursive will get a full set of forward declarations, so we should ignore them for the purpose of sorting. Reviewed-by:

Track which nests are recursive. Non-recursive nesting gets rendered in C as directly nested structs. For recursive ones we need to put a pointer in, rather than full struct. Track this information, no change to generated code, yet. Reviewed-by:

Ahmed Zaki says: ==================== Support symmetric-xor RSS hash Patches 1 and 2 modify the get/set_rxh ethtool API to take a pointer to struct of parameters instead of individual params. This will allow future changes to the uAPI-shared struct ethtool_rxfh without changing the drivers' API. Patch 3 adds the support at the Kernel level, allowing the user to set a symmetric-xor RSS hash for a netdevice via: # ethtool -X eth0 hfunc toeplitz symmetric-xor and clears the flag via: # ethtool -X eth0 hfunc toeplitz The "symmetric-xor" is set in a new "input_xfrm" field in struct ethtool_rxfh. Support for the new "symmetric-xor" flag will be later sent to the "ethtool" user-space tool. Patch 4 fixes a long standing bug with the ice hash function register values. The bug has been benign for now since only (asymmetric) Toeplitz hash (Zero) has been used. Patches 5 and 6 lay some groundwork refactoring. While the first is mainly cosmetic, the second is needed since there is no more room in the previous 64-bit RSS profile ID for the symmetric attribute introduced in the next patch. Finally, patches 7 and 8 add the symmetric-xor support for the ice (E800 PFs) and the iAVF drivers. ==================== Link: https://lore.kernel.org/r/20231213003321.605376-1-ahmed.zaki@intel.comSigned-off-by: -

Allow the user to set the symmetric Toeplitz hash function via: # ethtool -X eth0 hfunc toeplitz symmetric-xor All existing RSS configurations will be converted to symmetric unless they have a non-symmetric field (other than IP src/dst and L4 src/dst ports) used for hashing. The driver will reject a new RSS configuration if such a field is requested. The hash function in the E800 NICs is set per-VSI and a specific AQ command is needed to modify the hash function. Use the AQ command to enable setting the symmetric Toeplitz RSS hash function for any VSI in the new ice_set_rss_hfunc(). When the Symmetric Toeplitz hash function is used, the hardware sets the input set of the RSS (Toeplitz) algorithm to be the XOR of the fields index by HSYMM and the fields index by the INSET registers. We use this to create a symmetric hash by setting the HSYMM registers to point to their counterparts in the INSET registers: HSYMM [src_fv] = dst_fv; HSYMM [dst_fv] = src_fv; where src_fv and dst_fv are the indexes of the protocol's src and dst fields.
